  • The seismic cone test 
    Heymann, Gerhard (South African Institution of Civil Engineering, 2003)
    The seismic cone test is an in situ test used to measure body wave velocities in soils. Geotechnical parameters that may be derived from the test include void ratio, small strain stiffness and Poisson's ratio. In addition, ...
  • Selected implications of a hyper-connected world on pavement engineering 
    Steyn, Wynand Jacobus Van der Merwe (Springer, 2020-11)
    The world is becoming a hyper-connected environment where an abundance of data from sensor networks can provide continuous information on the behaviour and performance of infrastructure. The last part of the 3rd Industrial ...
  • Shear wave velocity of gold tailings 
    Chang, H.P.N.; Heymann, Gerhard (South African Institution of Civil Engineering, 2005)
    To evaluate the liquefaction potential of tailings impoundments, the in situ void ratio and the effective stresses are required. While stresses can be estimated with relative accuracy,the void ratio of tailings has proved ...
  • Simplified HYMOD non-linear simulations of a full-scale multistory retrofitted RC structure that undergoes multiple cyclic excitations – an infill RC wall retrofitting study 
    Markou, George; Mourlas, Christos; Bark, Hussein; Papadrakakis, Manolis (Elsevier, 2018-12)
    Having the ability to assess the earthquake resistance of retrofitted reinforced concrete (RC) structures through accurate and objective nonlinear cyclic analysis is of great importance for both scientists and professional ...
  • Slab track test section for University of Pretoria railway research facility 
    Grabe, Petrus Johannes; Wagner, Heinrich (South African Institution of Civil Engineering, 2018-05)
    Slab track is an alternative to conventional ballasted track and has been used locally and internationally for more than 50 years. The scale of implementation has varied from extensive, in the case of some metro and ...
  • Small-scale hydropower development for rural electrification in South Africa 
    Van Dijk, Marco; Van Vuuren, Fanie; Bhagwan, Jay; Loots, Ione (South African Institution of Civil Engineering, 2014-06)
    Although the electrification of urban areas and some informal settlements in South Africa has been achieved during recent years, many rural areas still require intervention to provide a reliable and sustainable electricity ...
  • smAvo and smaTo : a fruity odyssey of smart sensor platforms in Southern Africa 
    Broekman, Andre; Steyn, Wynand Jacobus Van der Merwe; Steyn, J.L.P. (Johannes); Bill, Malick; Korsten, Lise (Elsevier, 2020-10)
    Avocado and tomato production are key agricultural sectors for many economies including South Africa. The quality of avocadoes and tomatoes that reach consumers is directly dependent on the handling at the postharvest ...
  • Social life cycle inventory for pavements – a case study of South Africa 
    Blaauw, Sheldon Alfred; Maina, J.W. (James); Grobler, Louis J. (Elsevier, 2021-06)
    Social consideration, assessed using a social life cycle assessment (S-LCA), is a relatively new concept that has yet to be standardised. Attempts at measuring social sustainability in pavement management have been made ...
  • Soil collapse from an effective stress perspective 
    Brink, George Eksteen; Heymann, Gerhard (South African Institution of Civil Engineering, 2014-10)
    The behaviour of collapsible soil is often quantified by conducting a Collapse Potential Test or double oedometer test. However, these tests interpret the soil behaviour in terms of total stress, while it is well known ...
  • Some lessons from Lagos 
    Venter, C.J. (Christoffel Jacobus) (South African Institution of Civil Engineering, 2009-09)
    In June 2009 the City of Tshwane's BRT Project Office hosted a World Bank-led workshop on public transport restructuring. A highlight was the presentations made by colleagues from Nigeria on their experiences with implementing ...
  • Some round timber pole connections 
    Burdzik, W.M.G. (South African Institution of Civil Engineering, 1997)
    The paper looks at alternative round timber pole connections that make monoplanar structures and trusses a possibility. Three different systems are discussed and where test results are available, these are compared with ...
  • Spherical void formers in concrete slabs 
    Marais, Cornelle; Robberts, John M.; Janse van Rensburg, Ben W. (South African Institution of Civil Engineering, 2010-10)
    Large span concrete flat-slab systems with internal spherical void formers (SVF) have been used in Europe for over a decade. They are bi-axially reinforced concrete flat-slab systems with a grid of internal spherical void ...
  • Splitting tensile test for fibre reinforced concrete 
    Denneman, Erik; Kearsley, Elsabe P.; Visser, Alex T. (Springer, 2011-10)
    The splitting tensile test is a much used method to determine the tensile strength of concrete. The conventional test procedure is known to have a number of limitations related to size effect and boundary conditions. ...
  • State-of-the-art investigation of wind turbine structures founded on soft clay by considering the soil-foundation-structure interaction phenomenon – optimization of battered RC piles 
    Gravett, Dewald Zane; Markou, George (Elsevier, 2021-05)
    Nonlinear dynamic modelling of full-scale wind turbine structures and soil-structure interaction considerations using the 3D detailed approach is the most accurate method of investigating the mechanical response of these ...
  • The stiffess of unsaturated railway formations 
    Otter, Louise; Clayton, Christopher Robert I.; Priest, Jeffery A.; Grabe, Petrus Johannes (Sage, 2016-05)
    The rational design of a substructure to support a rail track requires an estimation of the stiffness value of the formation on which it is to be built. Stiffness values derived from back-analyses of deformations of the ...
  • Stochastic modelling for the maintenance of life cycle cost of rails using Monte Carlo simulation 
    Vandoorne, Rick; Grabe, Petrus Johannes (Sage, 2018-04)
    The need for decision support systems to guide maintenance and renewal decisions for infrastructure is growing due to tighter budget requirements and the concurrent need to satisfy reliability, availability and safety ...
